-Great overall stream quality (1080p)
-Got lag spikes after game 2 of Burden vs Alliance (guess that was on your the broadcasting side) and for several seconds at a time during the next game.
-Good color rendering and contrast
-Audio quality was fine as far as I can tell

How do you feel about the video quality? Resolution, framerate, color, contrast, etc.
- Video quality is good compared to twitch but is taking it's toll on the bandwidth too. I can watch high on twitch without lagging and it's stuttering abit in 480p for me.
(2mbps connection)

How is your connectivity to the stream? Do you experience lag? Reconnections? Down-rezzing? (if so, where are you located?)
Connectivity is fine. Audio is abit choppy sometimes on 480p. Literally unwatchable on 720p. Got an error that Video can't be played due to an unexpected error while scrolling up and down in the steam client.(I am watching in steam client since it doesn't support Mozilla).

How is the transcode quality?
480p is kinda blurry to the point of unwatchable for me. if it could use some less bandwidth maybe?

Do you have any other feedback about the stream?

I'm enjoying the quality. It's way more respectful to the In-Game Dota feel than twitch.
However, it's not +720p, but it's mostly due to my poor Internet. But at least changing quality is not causing some latence or so.

That's cool. Last thing I would want is a way to watch the stream in another window.

just for a 720p 45-55% of my cpu was working for it, watchable.
( i was watching on steam web browser , i3-2365 1.4GHz, using wondows 7. my laptop is an Asus F550C)
if i disconnect my charger i get something like 3-4 fps both in audio and video.
480p and sub are watchable even with my charger disconnected.
for comparison i can watch Twitch on "high" with my charger disconnected as it requires only 13% of my cpu.

ofc i am on a shitty machine and most steam users have better stuff( and yet i can run Dota2! painfully.) but some have it like me, or just want to watch stuff while also having something casually running in the background or while being on a battery(phones?).
